FASTENING STRIP.

Application filcd'April as, 1922. Serial in). 557,101.

To all whom it may concern: i

- Be it known that 1, E1110 E. Hanna citizen oi the of Illinois, have invented certain new and useful Improvements in Fastening Strips, of which the following is a full, clear, and ex ct specification. 7

My invention is concerned with building materials and isdesigned to produce a novel it'astenlng strlp that iscapable of a Variety.

of uses. a To illustrate my invention, I annex hereto a sheet of drawings, in which the same reference characters are used to designate identical parts in all the figures, of wl11ch,-

Fig. 1 a perspective view of a portlon of a concrete floor having two of my fastening strips en'ibedded in the surface thereof;

Figs. 2, 3 and -i: are aside elevation, cross section and top plan View, respectively, of the fastening strip shown in 1; 4

Fig. is a view similar to Fig. ;1', but showing-a different design of strip" embedded in the floor so thatits top surface is flush with the top of the floor,

Figs. 6, 7 and 8 are a side elevation, cross section, and top plan View, respectively, of the :liastening strip shown in Fig. and

Fig. 9 is a perspective view of a portion of a concrete floor and ceiling showing my fastening strips embedded in the bottom of the concrete joists to furnish a means tor securing the ceiling thereto.

In carrying out my invention, I employ a central strip 10, preferably composed of soft wood, but which may be a fiber composition made up of sawdust and suitable binding material, or something of the same general character. These strips are either cut or molded to the desired shape in cross section, the strips shown in Figs. 1 to 1 preferably being pentagonal in cross section, the upper portion of the strips being in the form of a rectangle with an inverted equilateral triangle secured on the under side thereof. In the form shown in Figs. 5 to 9, inclusive, the strip 10 is in the form of an inverted equilate 'al triangle.

This fiber strip is surrounded by a metallic sheathing 11, which is preferably formed from a strip of sheet metal, which strip is preferably perforated, preferably by expanding two sections, 12 and 13, there of, in the customary manner of making expanded metal. Where the cross section .lnitcd States, and a resident of" Chicago. 111 the count 0t Cook and State of thestrip' 1O shownin Figs. 1 to 4 is employed, the strip may be considered as made up otsix sectionslt, 15, 16, 17, 18 and 19, the sections 14: to 18 forming the live sides of the completed strip, While the sec tiont '19'torms the anchoring insert, and the aperture-d portion 12 is in the portion'lti, as that is the uppermost, and the apertures are employed to permit flooringtobenailedonto the strips whenthey are employed as shown in Fig. 1 or in Fig. 5. The aperture'd or expanded portion 13 is :located in thei portion 19, the apertures being employed so that the concrete of the floor '20 will passthrough the apertures and anchor the strips in place when the-concrete has hard deneci. To secure the sheathingin placeyI form on the free edge of the portion 1.4: the series oi. tongu s 21, which pass through 1 corresponding apertures 22'formed llT'EllL. strip .at the junction of the parts 18 and. 19, and are pressed-into engagement with the adjacent surtaecfl'as seen in and 6. a i

The form shown in Figs. l to a fis 'enr' ployed where it is desired to secure the wooden flooring (not shown) ashort dis tance above the concrete floor 2c, and in this case, as soon as the concrete floor is poured and before it has time to harden. materially, the strips are put into place, which can be readily done by shoving them back and forth on the floor with the portion 19 vertical until they, have been Worked down so that the angles between the parts 14 and 15 and 17 and 18 are at the surface of the floor. Where the wooden flooring is to be secured directly on top of the concrete fioor 20, as in Fig. I), the. shallower strips are forced into place in the same manner until their horizontal surfaces are flush with the surface of the poured concrete, as shown in Fig. 5. Of course it will be understood that when the Wooden floor-- ing is put in place, it is secured by nailing through the wooden flooring and the apertures 12 into the wooden or fibrous strip 10, and the flooring is secured in place more permanently than it would be with ordinary strips, for the reason that the nails, as indicated in dotted lines in Fig. 1, will \strike the angular metallic bottom of' the strips and be bent over so as to clinch them to the strips, so that they cannotbe accidentally pulled out or even readily pulled out intentionally.

In Fig. 9, I- illustrate another useof the strips shown in Figs. 5 to 8, where they are placed in an inverted position on the wooden bottoms of the forms for the concrete joists23 shown in connection with the concrete floor 20 of Fig. 9. hen the concrete ispo uredand has hardened, and the forms are removed, the fastening strips arein place with.

the fastening sides inverted, so that the celling 24 canbe nailed in place as indicated in Fig. 9.

While I have shown and described my in.-

venticn as, embodied in the form which I at present consider best adapted: to carry out its purposes, it will be understood that it is capableof some modifications, and that I do not desire toibe limited: in the interpretation of the following'claims except as may be necessitated by the state of the prior art.

That-I claim as new, and desire tosecure by: Letters- Patent of the United States, is: 1:. As a new and useful article. of manufacture', a strip of fibrous material enclosed on' all sides. thereof by a metallic sheathing,

said sheathing being provided with means for anchoring it in place.

2. As a new and useful article, of manufacture, a strip of fi'brous material enclosed onall sides thereof by a metallic sheathing,

facture, a strip of fibrous material enclosed on all. sides thereof by a metallicsheathing, said. sheathing having projecting therefrom a.1; erforated .rib, for the purpose described.

5. As a new and useful article of manufacture, a strip of fibrous material enclosed by a metallic sheathing,said sheathing having" projecting therefrom a rib, expanded to form perforations therein, for the purpose described.

6. As a new and useful article of manu facture, a strip of fibrous material enclosed by a metallic sheathing, said sheathing be ing formed of a sheet metal strip shaped with a plurality of angles, with connecting means forthe edges at one angle, and an extension beyond said connected' angle.

7. As a new and useful article of manufacture, a strip of fibrous material enclosed by a. metallic sheathing, said sheathing being formed of a sheet-metal strip shaped with: a plurality of angles, a line of apertures inv the strip at one angle and corresponding tongues formed on another edge to enter. the apertures, and a perforated portion extending; beyond said line of apertures.

8. As a new and useful articlev of manufacture, a strip of fibrous material enclosed on all sides thereoffby a metallic sheathing,

said sheathing having, projecting therefrom means forv anchoring the same to a bed of plastic material.

In witness whereof, I have hereunto set my hand and aflixed my seal, this 19th day of April, D. 1922;
